Basic functions

Applicable phase wire

PMU1A PMU2A
(Electric (Power
power) two-system)
• Set the phase wire to be measured.
• Setting range: Single-phase 2-wire, single-phase 3-wire, 3-phase 3-wire, and 3-phase
4-wire (initial value: 3-phase 3-wire)
*1. For PMU2A (power two-system), 3-phase 4-wire cannot be set.
*2. CTD8E (CT expansion) can perform the two-system measurement only when it is
connected to PMU2A (power two-system).

Synchronization selection for measuring block

PMU1A PMU2A
(Electric (Power
power) two-system)
× ×
• Set the voltage system synchronized with a measuring block.
• Setting range: System 1, system 2 (initial value: system 1)
The measuring blocks are divided into measuring block 1 and measuring block 2, which are
assigned to system 1 and system 2, respectively, to perform power measurements. For
PMU1A and PMU2A, since their measuring blocks and voltage systems are fixed, the setting
of synchronization selection for measuring block is not required.

Dedicated CT type

PMU1A PMU2A
(Electric (Power
power) two-system)
• Set the dedicated CTs to be used.
• The dedicated CTs are as follows.

• Setting range: 5 A, 50 A, 100 A, 200 A, 400 A, 600 A (initial value: 100 A)
* CTD8E (CT expansion) can perform the two-system measurement only when it is
connected to PMU2A (power two-system).
* PMU2A (power two-system) can set dedicated a CT type for each system. CTD8E (CT
expansion) can set a type for each measuring block.
